The four, clearly written.

I picked up the plug with four on it, clearly printed. Master John nodded and I handed it to him. He helped me insert my new plug and then we settled down at an angle so we could both watch Mark and Mistress. He was leaning back in a chair and I had my head in his lap. I took his cock in my mouth and watched as Mark finished making out with Mistress and then stood up.

She looked up at him, now naked in the bathtub and reached over the edge of the bathtub to pick up a knife. She held it out to him ritualistically and I watched Mark’s cock harden further. “Stand up, turn to face them,” Mark said.

Watching this woman turn around with a noose around her neck, naked with Mark behind her I couldn’t help but pant onto Master John’s cock. “Settle, this is nothing compared to what I have planned for you,” he told me.

Mark pulled on the rope to start it synching around Mistress’ neck and I heard her moan, a few moments later I saw his cockhead poke out between her legs, rubbing against her cunt.

They shifted uncomfortably for a little bit before Mistress moaned again and Master John and I watched Mark sink his cock between her lips. Mark pulled the roped a little tighter as he asked, “So are you fertile?” Mistress croaked a yes, “You are going to take my baby away from Kimmie?” he brought the knife around her body and held it against her stomach as she grabbed at the noose. “Are you?” She croaked another yes as he continued to fuck her.

“If you’re going to be my breeding cow, and let me cut you, what good will she be?” He demanded of her as he pressed the tip of the blade into her flesh. Mistress tried to say something but couldn’t breathe to speak. Mark jerked on the rope and I watched Mistress’ legs sway in the bathtub as it trying to find purchase as she shuddered and came over his cock. As he lowered the rope he pushed the blade deeper into her as Master John said to me. “That’s where I am going to make a new fuck hole.”

As I came at his words Mark insisted on an answer from Mistress, “She will be a disposable toy for Master John,” she croaked again.

Mark pushed the short blade hilt deep into her abdomen as he pulled on the rope, the cinch cutting off her breath before she could scream. “That’s right, he’s going to fuck her, and cut her and use her, but you are going to steal her kid from me.”

Mark let the knife go and I watched as it bounced off the side of the tub to land on the floor. Both his hands went to the rope and he pulled more while he continued to fuck her from behind. She was shaking and flopping about and I found myself drooling with arousal over Master John’s cock.

“I can do that to you if you wish it, but I won’t guarantee I will stop. See that loop near Mark’s leg? I would tie you up, let you hang there when I was done.” I screamed onto his cock as I came at the fucked up thought of Master John hanging me for good.
